Nordvestfjord: a major East Greenland fjord system
Fjords are deep valleys that have been flooded by encroaching seawater after ice retreat (Syvitski et al. 1987). They are produced mainly by glacial erosion, with the ice sometimes exploiting pre-existing river systems or structural weaknesses. Fjords are found in mountainous terrain in all areas affected by large glaciers and ice sheets, both today and during full-glacial periods. They are therefore a distinctive landform indicative of past glacial activity.
